Nitrogen (N) enrichment has direct effects on ecosystem functioning by altering soil abiotic conditions and indirect effects by reducing plant diversity and shifting plant functional composition from dominance by slow to fast growing species. Litter decomposition is a key ecosystem function and is affected by N enrichment either by a change in litter quality (the recalcitrance of the plant material)

Sensory systems perform fitness‐relevant functions, and specialized sensory structures allow organisms to accomplish challenging tasks. However, broad comparative analyses of sensory morphologies and their performance are lacking for diverse mammalian radiations. Neotropical leaf‐nosed bats (Phyllostomidae) are one of the most ecologically diverse mammal groups; including a wide range of diets and

Adjustments in root biomass allocation, root morphology, carboxylate exudation and mycorrhizal symbiosis are well‐known strategies for plants to cope with phosphorus (P) deficiency. Large genotypic variation in these functional traits has been demonstrated within numerous species. Yet, whether these functional traits are coordinated differently among genotypes of a species to enhance P acquisition

Fleshy fruits have evolved multiple times and display a tremendous diversity of colors, shapes, aromas, and textures. For over a century this was attributed, at least in part, to frugivore‐driven selection. The dispersal syndrome hypothesis posits that fruits and frugivores co‐evolved, each exerting sufficient selective pressure on one another, and resulting to in suites of fruit traits that match

Evolutionary theory predicts that the capacity to acclimate should be favoured in variable environments. However, perfect compensation for thermal variation is rare and the capacity for thermal acclimation can vary considerably between individuals within natural populations. This variation may be explained by costs associated with acclimation, but it is not clear what these costs are. We tested the

1.Litter decomposition in sunny, semiarid and arid ecosystems is controlled by both biotic factors including litter traits and abiotic factors including UV light, but for wood decomposition it still remains uncertain which of these environmental factors are the predominant controls among different woody species. In these dry ecosystems it is likely that the stem diameter and spatial position of the

1. Selecting suitable species for vegetation restoration presents a notable challenge for land managers and scientists. Recently developed trait‐based approaches may be an effective means of overcoming this challenge. However, we lack a trait‐based species screening model that can be used to select potential species for restoration of degraded ecosystems.

Vectors and viruses exist in communities consisting of many interacting species. Although the cascading effects of predators or parasitoids on disease spread via direct effects on vectors have been investigated, little is known about the effects of other free‐living species in communities on the transmission of vector‐borne viruses via indirect (host‐plant mediated) effects on vectors. In the present

Northern peatlands consist of a mosaic of peatland types that vary spatially and temporally and differ in their methane (CH4) production. Microbial community composition and environment both potentially control the processes that release carbon from anoxic peat either as CH4 or as carbon dioxide (CO2), a less potent greenhouse gas than CH4. However, the respective roles of these controls remain unclear

Selection pressures along climate gradients give rise to predictable variation in plant functional traits of individual species suggestive of local adaptation. Species whose ranges include winter rainfall, Mediterranean climates, or other strongly seasonal climates, may be exposed to divergent selection pressures at different ends of seasonality gradients. Here, we evaluate how rainfall seasonality

Many animals improve their foraging success by producing signals that exploit the sensory biases of potential prey, but the specific properties that make these sensory traps effective remain unclear. We combine field experiments with phylogenetic comparative analyses to investigate the visual luring properties of different signal designs in web‐building spiders. Our field experiments used cardboard

The life cycles of animals vary in relation to local climate, as a result of both direct environmental effects and population‐level variation in plastic responses. Insects often respond to the approach of winter by entering diapause, a hormonally programmed resting state where development is suspended and metabolism suppressed. Populations often differ in the duration of diapause, but the adaptive

The field metabolic rate (FMR) of an endothermic animal represents its energy expenditure in a natural environment, or its energy budget, and its field water flux (FWF) reflects the animal's water requirements. We examined FMR of 103 species and FWF of 75 species of adult birds from direct field measurements using the doubly labelled water method, and used the phylogenetic generalized least squares

Cover image: Podarcis lizard from the Southern Adriatic (Croatia). These lizards often include plant matter into their diet, and some populations have rapidly adapted to these novel diets after having been introduced on some islands. Epigenetic mechanisms have been invoked to explain the rapid phenotypic changes that have taken place in these introduced populations. Our Special Feature: Epigenetics

We generally assume that animals should maximize information acquisition about their environment to make prudent decisions. But this is a naïve assumption, as gaining information typically involves costs. This is especially so in the social context, where interests between interacting partners usually diverge. The arms race involved in mutual assessment is characterized by the attempt to obtain revealing
